Abstract
- Based on the hydrothermal in situ acylation reaction of benzene-1,2,4-tricarboxylic acid (btca) with N 2 H 4 ·H 2 O, two containing-4-carboxylphthalhydrazidate Mn 2+ /In 3+ coordination polymers, [Mn(cpth)(phen)] 1 and [In(cpth)(ox) 0.5 (phen)]·H 2 O 2 (cpth = 4-carboxylphthalhydrazidate, phen = 1,10-phenanthroline, ox = oxalate), were obtained and characterized by elemental analysis, IR spectroscopy, X-ray powder diffraction (XRD), thermogravimetric analysis (TGA), and single-crystal X-ray diffraction. In compound 1 , the cpth ligands exhibit a μ 4 -bridging mode, which link Mn(II) centers into a 2-D layer structure with ancillary phen molecules. In compound 2 , the cpth ligands exhibit a μ 2 -bridging mode, which link In(III) centers into a binuclear unit. Ox ligands act as the second linkers, extending binuclear unit into a 1-D chain with ancillary phen molecules. Via N H⋯O interactions, compound 2 self-assembles into a 2-D supramolecular layer. The magnetic analysis indicates that there exists antiferromagnetic interactions between magnetic centers in compound 1 . The photoluminescence properties of compounds 1 and 2 were also investigated in an aqueous solution. [ABSTRACT FROM AUTHOR]
